Where do I even begin here.. Well, at the beginning. This book is really aimed at people who are both somewhat familiar with Linux and, at least conceptually with virtualization. In a nutshell, this book will take you through a soup-to-nuts clustered Proxmox install.
For a 300 page book, there is a pretty good amount of information to cover here and you start right out with an overview of then menu system – what to find on what tab and that sort of thing. This is followed very closely by actually setting up a basic cluster, the part of the first chapter that I spent the most time in. Once you have worked your way through that far, you are really already successfully running your own cluster and the rest of the book is your reference materials and in depth learning. You go through a lot of information on configuration files and shared storage solutions (which you really need for a clustered installation), networking, advanced configs for your virtual machines, high availability, troubleshooting issues, etc..
What I liked? Well, I think the book is layed out well, except for maybe placing the menu section before the install section of the first chapter. The book follows a sensical path throughout. The examples are great and clear as well as the diagrams. The book is not at all hard or too technical to follow for the subject matter. The troubleshooting section was a big help for me and I think a boon for the book. I really liked it and ended up with a working cluster at the end (actually somewhere in the middle).
Definitely another keeper. Mastering Proxmox is something you really should look into if you are at all interested in doing any computer virtualization. There is plenty in there to learn and for around $20 I don’t think you can beat the price!
